New Siding or New Windows: Which One Comes First?

Why the Order of Siding and Window Installation Matters

If you’re planning a big exterior home improvement project, you may be asking: Should I install new siding or new windows first? It’s a common question for Midwestern homeowners tackling remodeling projects.

Here’s the quick answer:

• Windows first: Often recommended so the siding can be cut and fit properly.
• Siding first: Sometimes makes sense if siding is severely damaged and exposing your home to weather.

The right choice depends on your home’s condition, your budget, and your remodeling goals. Not sure where to begin? Schmitt Roofing & Construction can help.

The Basics of Siding and Window Replacement

Siding and windows do more than make your home look good—they protect against moisture, drafts, and heat loss. In the Midwest, where harsh winters and humid summers are the norm, both play a vital role in keeping your home efficient and safe.

• Siding: Acts as the protective “skin” of your house, shielding it from wind, rain, hail, and temperature changes. Schmitt offers durable vinyl and metal siding options designed to stand up to Midwest weather.
• Windows: Provide natural light, ventilation, and insulation. High-quality windows reduce energy bills by preventing drafts and blocking UV rays.

Choosing the right sequence matters because these two systems work hand in hand to protect your home.

What to Consider Before Deciding

Before you decide whether siding or windows come first, take time to consider these factors:

• Condition of Existing Materials: If your windows are drafty or rotted, replace them first. If siding is failing and exposing the structure, siding may be urgent.
• Budget: Doing both together ensures the best fit and efficiency but requires a larger upfront investment.
• Project Goals: If your priority is curb appeal, siding might come first. For energy efficiency, start with windows.
• Scheduling: Coordinating both projects at the same time avoids duplicate labor costs and ensures seamless installation.

A professional inspection helps determine which option makes the most sense for your specific home.

New Siding vs New Windows: A Comparison

Here’s a side-by-side look to guide your decision:

Feature	New Windows First	New Siding First
Fit & Finish	Easier to cut siding around new frames	May require re-trim if windows replaced later
Energy Efficiency	Immediate savings on heating/cooling	Limited impact until windows are upgraded
Curb Appeal	Less visual change at first	Immediate boost in exterior appearance
Long-Term Savings	Better insulation upfront	May need rework if windows added later
Best Use Case	Drafty, outdated, or broken windows	Severely damaged or rotting siding

Why Many Experts Recommend Windows First

Ensures a Perfect Fit

Installing windows first allows siding contractors to custom-fit siding around new frames. This avoids awkward gaps and the need for extra trim later.

Improves Energy Efficiency Immediately

New windows seal drafts and improve insulation right away, which is especially valuable before another Midwest winter hits.

Saves on Labor Costs

Doing windows first prevents contractors from having to cut into freshly installed siding to accommodate new window dimensions.

When Siding Should Come First

Structural Protection

If your siding is cracked, warped, or allowing water into the home, it may be more urgent than window replacement.

Major Exterior Renovations

If you’re re-cladding your entire home, new siding may provide the transformation you want while buying time to budget for windows.

Safety Considerations

Failing siding can expose sheathing or framing to moisture, leading to rot and mold. In this case, siding should not be delayed.

Deep Dive: Why Order Matters

For Midwestern homeowners, return on investment is key. According to national remodeling reports, both siding and window replacements rank high for ROI, with siding averaging around 75% and windows around 70%. But the sequence affects how long you benefit from those returns.

• Windows First: You start saving on utility bills right away, while also improving resale appeal to buyers who value efficiency. 
• Siding First: You instantly boost curb appeal and protect your home, which can be crucial if you’re planning to list it soon. 

Ultimately, replacing both together provides the best long-term value, as contractors can integrate flashing, trim, and sealing in one seamless job.

Quick Checklist for Homeowners

• Inspect both siding and windows for damage.
• Decide whether energy efficiency or curb appeal is your top priority.
• Get quotes for both projects from a trusted contractor.
• Ask about combined project pricing for potential savings.
• Schedule work during mild Midwest weather for fewer delays.
